WEATHER STRIP.

Application filed September 7, 1926. Serial No. 133,926.

My invention relates to a strip arranged for use particularly upon windows to maintain a. resilient seal between the upper and lower sashes thereof.

It is an object of the invention to provide a closure between the adjacent ends of the upper and lower sashes of a window which will also act to prevent rattling, and which will allow movement of the sash as desired.

It is also desired to form the closure of resilient material which is shaped to lit the contour of the sash and allow a swinging movement of the upper sash without interfering with the weather-tight seal between the sash ends.

Referring to the drawings which are somewhat diagrammatic in their showing of the window, Fig. 1 is a side elevation of upper and lower window sash equipped with my invention. Fig. 2 is a similar view showing the lower sash partly raised, and Fig. 3 is a side view with the upper sash swung forwardly.

In the drawings the lower sash is represented at 1, the lower end 2 being beveled to fit the lower portion of the window frame, not shown. The upper end has the outward side thereof extended slightly at 3 and rounded on the arc of a circle for contact with the weather strip upon the upper sash 4.

The upper sash may be made as desired, the lower end being positioned closely adjacent the rounded side 3 of the lower sash.

Between the adjacent ends of the two sashes is a weather strip 5 understood .as extending the full width of the uppersash. Itconsists of a resilient plate of sheet metal, the upper side of which is secured by screws or otherwise to the inner side of the sash. The plate is bent inwardly toward. the upper end of the lower sash and has an area 6 curved to fit the rounded surface 3 of the lower sash. Below the curved area the lower edge is recurved'at 7 to form a blunt edge for contact with the lower sash.

In use, this weather strip fills the space between the adjacent sash ends to prevent the entrance of rain or wind. It also holds the sash resilientlyso as to prevent rattling of the sash in theframe. The lower sash is adapted to be raised, or the upper sash to be lowered, without interference. Also the circle, a plate of resilient sheet metal secured to the lower end of said upper sash and adapted to bear against the rounded face of said lower sash.

2. In a window, upper and lower sashes adapted to move relative to each other, a rounded projection formed upon one end of one said sashes, and a weather strip on the adjacent end of the other sash, said weather strip being shaped to fit said rounded projection to bear resiliently against the same.

3. In a window, upper and lower sashes adapted to slide vertically relative to each other, a strip of resilient sheet metal upon said upper sash projecting inwardly to bear against said lower sash, said strip and lower sash fitting together to allow the upper end of the upper sash to swing inwardly without interfering with the close fit of the strip between the sashes.

4. In a window, .an upper sash mounted to swing inwardly at its upperend, a strip of resilient sheet metal secured to the inner face of said sash at the lower end thereof and inclined forwardly out of the plane of said sash to contact with an adjacent part of the window in the manner described.

5. In a window, upper and lower sashes therein, and a strip of resilient-sheet metal secured to one sash and bearing resiliently against the adjacentsash to preserve a closure between said sashes when said upper sash is swung inwardly in the manner described.

In testimony whereof I hereunto affix my signature this 30 day of August, A. D. 1926.
